4 SAFETY PRECAUTIONS J Safety Signal Words This manual uses the following signal words to mark safety precautions for the E5AN/EN/CN/ GN. These precautions provide important information for the safe application of the product. You must be sure to follow the instructions provided in all safety precautions. WARNING Indicates information that, if not heeded, could possibly result in loss of life or serious injury. CAUTION Indicates information that, if not heeded, could result in relatively serious or minor injury, damage to the product, or faulty operation. J Safety Precautions CAUTION F Electric Shock Warning Do not touch the terminals while the power is ON. Doing so may cause an electric shock. Do not allow metal fragments or lead wire scraps to fall inside this product. These may cause electric shock, fire or malfunction. Never disassemble, repair or modify the product. Doing so may cause electric shock, fire or malfunction. The life expectancy of the output relays varies greatly with the switching capacity and other switching conditions. Always use the output relays within their rated load and electrical life expectancy. If an output relay is used beyond its life expectancy, its contacts may become fused or burned. Do not operate this product in flammable and explosive gas atmospheres. Use this product within the rated load. Not doing so may cause damage or fire. Use this product within the rated supply voltage. Not doing so may cause damage or fire. Tighten the terminal screws properly. Loose screws may cause malfunction. Tighten to a torque of : E5AN : 0.74 to 0.90 N m E5EN : 0.74 to 0.90 N m E5CN : E5GN: 0.74 to 0.90 N m Terminals1to6:0.23to0.25N m Terminals 7 to 9 : 0.12 to 0.14 N m Set all settings according to the control target of the product. If the settings are not appropriate for the control target, the product may operate in an unexpected manner, resulting in damage to the product or resulting in accidents. To maintain safety in the event of a product malfunction, always take appropriate safety measures, such as installing an alarm on a separate line to prevent excessive temperature rise. If a malfunction prevents proper control, a major accident may result. III

5 NOTICE Be sure to observe these precautions to ensure safe use. (1) Do not wire unused terminals. (2) Be sure to wire properly with correct polarity of terminals. (3) To reduce induction noise, separate the high-voltage or large-current power lines from other lines, and avoid parallel or common wiring with the power lines when you are wiring to the terminals. We recommend using separating pipes, ducts, or shielded lines. (4) Do not use this product in the following places: Places subject to dust or corrosive gases (in particular, sulfide gas and ammonia gas) Places subject to high humidity, condensation or freezing Places subject to direct sunlight Places subject to vibration and large shocks Places subject to splashing liquid or oily atmosphere Places directly subject to heat radiated from heating equipment Places subject to intense temperature changes (5) To allow heat to escape, do not block the area around the product. (Ensure enough space is left for the heat to escape.) Do not block the ventilation holes on the case. (6) When you draw out or draw in the internal mechanism from the housing (E5AN/EN/CN) or draw out the terminals (E5GN), never touch electrical components inside or subject the internal mechanism or terminals to shock. (7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the product. (8) On the E5AN/EN/CN, use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. On the E5GN, use AWG24 to AWG14 leads for terminal Nos.1 to 6 (with lead cover peel back allowance of 5 or 6 mm) and AWG28 to AWG22 leads for terminal Nos.7 to 9 (with lead cover peel back allowance of 5 or 6 mm). (9) Allow asmuch space aspossible between the E5AN/EN/CN/GN and devicesthat generatepowerful high-frequency noise (e.g. high-frequency welders, high-frequency sewing machines) or surges. (10) When executing self-tuning, turn the load (e.g. heater) ON simultaneously with the main unit. If you turn the main unit ON before turning the load ON, correct self-tuning and optimum control can no longer be obtained. (11) Use a 100 to 240 VAC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power supply matched to the power specifications of the E5AN/EN/CN/GN. Also, make sure that rated voltage is attained within two seconds of turning the power ON. (12) Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). (13) When mounting a noise filter on the power supply, be sure to first check the filter s voltage and current capacity, and then mount the filter as close as possible to the E5AN/EN/CN/GN. (14) Use within the following temperature and humidity ranges: Temperature: -10 to 55 C, Humidity: 25 to 85% (with no icing or condensation) If the E5AN/EN/CN/GN is installed inside a control board, the ambient temperature must be kept to under 55 C, including the temperature around the E5AN/EN/CN/GN. If the E5AN/EN/CN/GN is subjected to heat radiation, use a fan to cool the surface of the E5AN/ EN/CN/GN to under 55 C. (15) Store within the following temperature and humidity ranges: Temperature: -25 to 65 C, Humidity: 25 to 85% (with no icing or condensation) (16) Never place heavy objects on, or apply pressure to the E5AN/EN/CN/GN as it may cause it to deform and deteriorate during use or storage. (17) Avoid using the E5AN/EN/CN/GN in places near a radio, television set, or wireless installation. These devices can cause radio disturbances which adversely affect the performance of the E5AN/ EN/CN/GN. IV

10 CHAPTER 1 ABOUT COMMUNICATIONS METHODS 1.1 Outline J Introduction The program for the communications functions are created on the host computer, and the E5AN/EN/CN/GN s parameters are monitored or set from the host computer. Therefore, the description provided here is from the viewpoint of the host computer. CompoWay/F is OMRON s standard communications format for general serial communications. This format uses a standard frame format as well as the FINS* commands which have proven successful in OMRON s PLCs. Therefore, it can simplify communications between components and the host computer. * FINS (Factory Interface Network Service) TheFINSprotocol providesmessagecommunications between controllers in OMRON FA networks. The E5AN/EN/CN/GN have the following communications functions: Reading/writing of parameters Operation instructions Selection of setup levels Communications are subject to the following condition: Parameters can be written only when the communications writing parameter is set to ON (enabled).

11 1.1 Outline J Transmission procedure When the host computer transmits a command frame, the E5AN/EN/CN/ GN transmits a response frame that corresponds to the command frame. A single response frame is returned for each command frame. The following diagram shows the operation of the command and response frames. Command frame Command frame Host computer E5AN/EN/CN/GN Response frame Allow a wait time of at least 2 ms until the next command is sent after the host computer receives a response from the E5AN/EN/CN/GN. JInterface JWiring Communications with the host computer are carried out through a standard RS-485, RS-232C (RS-232C is only available with the E5AN/EN) interface. RS-485 RS-485 connections can be 1 : 1 or 1 : N. A maximum of 32 Units (including the host computer) can be connected in one-to-n systems. The total cable length is 500 m max. Use a shielded, twisted-pair cable AWG28 or larger for wiring the E5AN/ EN/CN, and AWG24 to AWG14 for wiring the E5GN.

13 1.1 Outline J Communications parameters The E5AN/EN/CN/GN s communications specifications are set in the communications setting level. These parameters are set on the E5AN/EN/ CN/GN s front panel. The following table shows the communications parameters and their setting ranges. Parameter Displayed Characters Setting Range Set Value Communications unit No. 0to99 0, 1 to 99 Baud rate 1.2 / 2.4 / 4.8 / 9.6 / 19.2 (kbps) 1.2 / 2.4 / 4.8 / 9.6 / 19.2 (kbps) Communications data length 7/8(bit) 7 /8(bit) Communications stop bit 1/2 1/2 Communications parity None / even / odd / / Highlighted characters indicate defaults. F Communications parameter setup Before you carry out communications with the E5AN/EN/CN/GN, set up communications unit No., baud rate and other parameters by carrying out the following procedure. For details of operations other than communications parameter setup, refer to the E5AN/EN/CN/GN User s Manuals. (1) Hold down the key for at least three seconds to move from the operation level to the initial setting level. (2) Press the key for less than one second to move from the initial setting level to the communications setting level. (3) Select the parameters as shown below by pressing the key. (4) Use the or keys to change the parameter set values. Communications unit No. Baud rate Communications unit No. Communications data length Baud rate Communications data length Communications unit No. Baud rate Communications stop bit Communications stop bit Communications data length Communications parity Communications parity Communications stop bit Communications parity E5AN/EN E5CN E5GN 1--5

14 CHAPTER 1 ABOUT COMMUNICATIONS METHODS F Communications parameter setup Note that communications parameters are enabled after they have been changed by resetting the controller. Communications unit No. ( ) This parameter is for setting the unit No. to each of the temperature controllers. This unit No. is set so that the host computer can identify the temperature controller when communications are carried out with the host computer. Set a unit No. within the range 0 to 99 for each temperature controller connected to the host computer on the network. Default is 1. When two or more temperature controllers are used, do not set the same unit No. Doing so will prevent normal operation. Baud rate ( ) This parameter is for setting the baud rate when communicating with the host computer. Set one of 1.2 (1200 bps), 2.4 (2400 bps), 4.8 (4800 bps), 9.6 (9600 bps) and 19.2 (19200 bps). Communications data length ( ) This parameter is for setting thecommunications data length. Set either of 7 bits or 8 bits. Communications stop bit ( ) This parameter is for setting the communications stop bit. Set either of 1 or 2. Communications parity ( ) This parameter is for setting the communications parity. Set one of none, even or odd. 1--6

16 CHAPTER 2 CompoWay/F COMMUNICATIONS PROCEDURES 2.1 Data Format Unless otherwise indicated, numbers in this manual are expressed in hexadecimal. Values in double quotation marks, such as 00, are ASCII. The number underneath each delimiter in a frame indicates the number of bytes. JCommand frame Text Node No. Sub-address SID Command text STX ETX BCC BCC calculation range STX Node number This (02) indicates the beginning of the communications frame (text). Always set this character in the first byte. When STX is received again during reception, reception is carried out again from the point where STX was received. This number specifies the transmission s destination. Specify the E5AN/EN/CN/GN s Communications unit No.. BCD range 00 to 99 and XX can be set. Specify XX for a broadcast transmission. No response will be returned forbroadcast transmissions. No responses will be returned from node Nos. set otherwise from the above. Sub-address This is not used on the E5AN/EN/CN/GN. Be sure to set the sub-address to 00. SID (service ID) This is not used on the E5AN/EN/CN/GN. Be sure to set the sub-address to 00. Command text ETX BCC Command text area. For details, see 2.2 Structure of Command Text. This (03) indicates the end of the text. Block Check Character The BCC result is found by calculating the exclusive OR of the bytes from the node No.uptoETX. 2--2

17 2.1 Data Format J BCC calculation example The BCC is formed by converting the 8-bit value obtained by converting the exclusive OR of the node No. up to ETX into two ASCII characters,and setting this to the BCC area. STX Node No. Sub-address SID Command text ETX BCC 02H 0(30H) 0(30H) 0(30H) 0(30H) 0(30H) 0(30H) 5(35H) 0(30H) 3(33H) 03H 35H BCC=30H 30H 30H 30H 30H 30H 35H 30H 33H 03H=35H Calculation result 35H is set to the BCC area. The symbol indicates exclusive OR operation and the H indicates hexadecimal. J Response frame STX Node No. Sub-address End Command text ETX BCC End Name Description Error Detection Priority 00 Normal completion The command ended normally without error. None 0F FINS command error The specified FINS command could not be executed. The FINS response should indicate why the command could not be executed. 10 Parity error The sum total of bits whose received data is 1 does not match the set value of communications parity Framing error Stop bit is Overrun error An attempt was made to transfer new data when the reception data was already full. 13 BCC error The calculated BCC value is different from the received BCC value. 14 Format error The command text contains characters other than 0 to 9, and A to F. This error is not applicable to the echoback test. (For details, see chapters 2.3 Echoback test. ) No SID and command text. Or, no command text MRC/SRC not included in command text 16 Sub-address error Illegal (unsupported) sub-address No sub-address, SID and command text Sub-address less than two characters, and no SID and command text 18 Frame length error The received frame exceeds the fixed (supported) number of bytes The end is returned to received command frames addresses to the self node. No response will be returned if all the items in the response frame are incomplete up to the ETX and BCC. Error Detection Priority indicates the priority when two or more errors occur simultaneously. 2--3

Example) 105.0! 1050! A JExample of end The following examples show an end when a command did not end normally. Example 1) Illegal sub-address, and no SID and command text Command Format Node No. Sub-address BCC STX 0 A ETX Response Format Node No. Sub-address End STX 0 A 1 6 ETX BCC End is 16 (sub-address error). This is because a sub-address was received and the sub-address error has a higher error detection priority than the format error. Example 2) No command text Command Format Node No. Sub-address SID STX ETX BCC Response Format Node No. Sub-address End STX ETX BCC End is 14 (format error). Example 3) All node Nos. not provided Command Format BCC STX ETX The node No. is lacking one character. Response Format No response 2--4

20 CHAPTER 2 CompoWay/F COMMUNICATIONS PROCEDURES 2.2 Structure of Command Text J PDU structure An MRC (Main Request Code) and SRC (Sub-Request Code) followed by the various required data is transferred to the command text. Service request PDU MRC SRC Data MRES (Main Response Code) and SRES (Sub-Response Code) are transferred following the above MRC/SRC. Data is then transferred following these MRES and SRES. Service response PDU (during normal operation) MRC SRC MRES SRES Data If the specified command text could not be executed, only the MRC/ SRC and MRES/SRES become the target response PDUs. Service response PDU (at non-execution of specified command text) MRC SRC MRES SRES MRES/SRES becomes the response except when processing ends in normal completion. J Area definitions JType (variable type) Areas comprise only variable area. The following defines variable area type s. Variabletype(1byte) MSB LSB Access size 11: Double-word Area 0:Setuparea0 1:Setuparea1 Read/Write 0: Read only 1: Read/write The following table summarizes setup areas 0 and 1. Area Setuparea0 Setuparea1 Description This area groups together the protect, operation and adjustment levels. This area groups together the initial setting, communications setting, advanced function setting and calibration levels. 2--6

21 2.2 Structure of Command Text The variable type is converted to 2-byte ASCII and loaded to the frame. The following table shows actually existent variable types. Variable type Description C0 Double-word data. R/O (read only) parameter for setup area 0. C1 Double-word data. R/W parameter for setup area 0. C3 Double-word data. R/W parameter for setup area 1. * Setup area 1 has no R/O (read only) parameters. Therefore, variable type C2 does not exist. JAddresses Each of the variable types is appended with an address. Express addresses in 2-byte hexadecimal, and append with its access size. JNumber of elements Thenumberofelementsisexpressedin2-bytehexadecimal.Specify the number of elements within the range 0 to 2. For example, when the number of elements is 0002, this specifies two items of data from the address.

F AT execute/cancel Set AT (auto-tuning) to execute or cancel according to related information.this instruction can beaccepted at setup area 0 only.however, note that an operation error is generated in the following instances: When the run/stop parameter is set to stop When the instruction is issued in setup area 1 When the ON/OFF control F Write mode Set either the backup mode or RAM write mode according to related information. This instruction can be accepted at both setup areas 0 and 1. F Multi- -SP Set four set points beforehand in the adjustment level so that you switch to a desired set point

30 CHAPTER 2 CompoWay/F COMMUNICATIONS PROCEDURES Write mode Backup mode RAM write mode Description Writing is carried out to EEPROM when the parameters in the operation/adjustment levels (excluding R/O parameters) are written by communications. Writing is not carried out to EEPROM when the parameters in the operation/adjustment levels (excluding R/O parameters) are written by communications. However, note that parameters can be changed by operating the keys on the front panel of the controller. When the RAM write mode is changed to the backup mode, the parameters in the operation/adjustment levels (excluding R/O parameters) are written to EEPROM. The RAM write mode is enabled only when the communications writing parameter is set to ON: enabled. So, when the communications writing parameter setting is changed to OFF: disabled, the parameters in the operation/adjustment levels (excluding R/O parameters) are written to EEPROM even if the RAM write mode is set to disabled. F Save RAM data This instruction writes the parameters in the operation/adjustment levels (excluding R/O parameters). This instruction can be accepted at both setup areas 0 and 1. F Software reset This instruction resumes processing after the power is turned OFF. This instruction can be accepted at both setup areas 0 and 1. No response will be returned for this operation instruction. F Move to setup area 1 This instruction moves to setup area 1 and can be accepted at both setup areas 0 and 1. However, note that when initial setup/communications protection is set to 2, an operation error is generated, and move to setup area 1 is forbidden. When this move is carried out from setup area 0, the display indicates the input type in the initial setting level. When this operation instruction is issued in setup area 1, the display will not change. F Move to protect level This instruction moves to the protect level and can be accepted only in setup area 0. When this instruction command is issued in setup area 1, an operation error is generated, and move to setup area 1 is forbidden
